Question

The specific heat capacity of the metal was 900 J/kg °C
Calculate the change in thermal energy of the metal during 240 seconds.

You will get brainliest if you explain how you got the answer

Answer 1

To calculate heat capacity, use the formula: heat capacity = E / T, where E is the amount of heat energy supplied and T is the change in temperature.

Here,

Specific heat capacity =  900 J/kg °C

Time(T) = 240 s

Thermal(heat) energy(E) = ?

E/T = Specific heat capacity

⇒E/240 = 900

⇒E = 900*240

⇒E = 216000 Joules

or, E = 216 kJ
